Surat, a major city in Gujarat, is located on the banks of the Tapi River. The river flows through the city and has been crucial to its historical development as a port city.

Badrinath, one of the Char Dham pilgrimage sites, is located on the banks of the Alaknanda River in Uttarakhand. The Alaknanda is one of the two headstreams of the Ganga.
